HEAT EXCHANGER Russian patent published in 1994 - IPC

FIELD: heat power engineering. SUBSTANCE: heat exchanger is provided with transverse partitions which form overflow ports together with the housing for inter-tube medium. Ports have different flow area. Knurling on the surface of the heat exchange tubes is made in form of spherical segments. Gaskets are provided with grooves whose form in longitudinal section is similar to that of the circular segments. These grooves bring tubes in communication with each other. EFFECT: intensification of heat exchange and reduction of hydraulic resistance. 7 cl, 4 dwg
